After the discovery of gold on the Cuyuni, the higher 
Essequebo was prospected— then the Puruni — the Po- 
taro — the Conowarook — the Demerara — the lower Esse- 
quebo— the Barama — and lastly the Barima. 
It is not until 1884 that we have any official record of 
the gold produced in the colony, — and it is very likely 
that for every ounce registered there were two ounces 
not officially recorded.

The yield in Dutch Guiana for 1883 was 23,849 ounces 
and it increased very gradually up to 1887 when it was 
27,456 ounces, more than twice as much as British 
Guiana. From 1887 until 1889 there was a considerable 
falling off, but in 1890 the production rose again to 
25,048 ounces, less than half the production of British 
Guiana for the same year. 
The geographical distribution of gold in the three Gui- 
anas appears to be in a broad belt running about North- 
west and South-east from the Orinoco to the Brazilian 
frontier of French Guiana. 
In French Guiana the Rivers Sinnamary, Mana, Ap- 
pronage and Maroni have been worked and some of the 
placers as St. Elie and Dieu Merci have been celebrated 
for their immense richness. 
In Dutch Guiana the Maroni with its tributaries the
